It's not you, it's us. Contrary to some of the lists we've put out, we don't actually support the Kiiroo Onyx/Pearl yet. We've had some issues trying to get it to work over Bluetooth 4, and we don't have a Bluetooth 2 core in the C# code yet. That's coming fairly soon, as we need it for the Onyx/Pearl, OhMiBod, Wiimote, and possibly some other stuff. We're also planning a serial core to work with either Bluetooth SPI or actual serial ports for things like the ET-312. Mostly it's just a matter of us having time to get all of this developed.
We are certainly interested in helping out for complex setups like this, and I'd love to see a serious kit setup hooked into this. I'll try to let you know when we've got the relevant parts in.
